Abstract: The present invention relates to a method and an arrangement for resource allocation in a packet transmission network including at least one link ( 19 ). According to the invention the following steps are performed: Determining link resource status. If link congestion is determined then: determining if it is possible to allocate more link capacity, allocating more link capacity when it is possible to allocate more link capacity, and alleviating link congestion using Active Queue Management when it is not possible to allocate more link capacity.

Abstract: The present invention pertains to the field of methods and apparatuses relating to radio communication; and in particular to the part of this field that concerns cellular radio communication. The present invention addresses mainly the problem of improving reliability and communication quality in a cellular radio communication system (1). According to the invention, it is determined whether one of an uplink (25) or a downlink (25) of a radio channel (23) is subject to a Rayleigh fading dip. If it is determined that one of the uplink (25) or the downlink (27) is subject to a Rayleigh fading dip, it is then determined whether it is necessary to execute a countermeasure in order to avoid the negative influences of Rayleigh fading on the channel (23). The invention is not limited to improving conditions on one channel but may be employed to any number of channels used for communications in the cellular radio communication system (1).
